The Touschek lifetime is the function of the energyacceptance of the storage ring.
托歇克寿命将是影响束流寿命的最主要因素,它主要受限于储存环的能量接受度。

Calculation shows that large energyacceptance with good resolution can be achieved for given electron spectrum by proper selection of foil thickness and spacing when using TRG spectrometer.
But there's some debate in the Western camp over any deal that could be taken as de-facto acceptance of Iran's ongoing enrichment to the 3.5% level for energy purposes.
